The Caatinga is the only biome found exclusively in Brazil and is home to the largest contiguous area of seasonally dry tropical forest in the world. However, anthropogenic activities such as cattle ranching, agriculture and firewood exploitation have caused large-scale environmental degradation processes that, together with climate change, could even lead to desertification. A study of cattle ranches in the semi-arid region of the state of Pernambuco found that simply stopping grazing did [...]

If you've ever eaten a pomegranate, you'll know that a great deal of the fruit is composed of its thick skin – which simply gets thrown away. Soon, however, that skin could be used in an edible coating which will help keep strawberries from spoiling. Although all fruits are prone to spoilage, strawberries have a particularly short shelf life. This is partially due to the fact that they're very moist and quite acidic, both of which make them ideal habitats for fungi. [...]

A method using free software and a drone with a low-cost camera has made it possible to select drought-tolerant corn plants. The tool contributes to the selection of plants that can better withstand water stress, one of the impacts of climate change on agriculture. The results of the experiments were published in an article in the Plant Phenome Journal. The authors are associated with the Genomics for Climate Change Research Center ( GCCRC ), an Engineering [...]

The gene encoding an enzyme from a firefly, discovered at the Sorocaba campus of the Federal University of São Carlos (UFSCar) in Brazil, has given rise to a biosensor capable of detecting pH changes in mammalian cells – which could be useful, for example, in studying diseases and assessing the toxicity of a drug candidate. The luciferase from the species Amydetes vivianii changes color from bluish-green to yellow and red as acidity decreases in fibroblasts, the most common [...]

The benefits of weight training are many: it promotes gains in strength and muscle mass, reduces body fat, and contributes to well-being and mental health. And now a study carried out at the State University of Campinas (UNICAMP), in the state of São Paulo, Brazil, has demonstrated another important effect: it protects the brains of older people against dementia. The results were published in the journal GeroScience. The study involved 44 people with mild cognitive impairment – [...]

A new edible film made from pomegranate peel and squid shells can help strawberries stay fresh for much longer, according to scientists in Brazil. This natural coating could double the shelf life of strawberries and prevent them from drying out or growing mold too quickly—all without changing their taste or smell. The film was developed by researchers at the University of São Paulo (IQSC-USP), along with teams from EMBRAPA Instrumentation and the Federal University of [...]

A new study from Brazil suggests that weight training can help protect the brain from dementia, especially in older adults already at risk. Researchers at the State University of Campinas (UNICAMP) found that regular strength training not only improved memory but also helped prevent brain shrinkage linked to Alzheimer’s disease. The study, published in GeroScience, involved 44 older adults with mild cognitive impairment (MCI)—a condition where memory and thinking skills are [...]

Researchers at the Tupa campus of Sao Paulo State University (UNESP) have introduced a new geospatial intelligence method designed to improve the speed and precision of land use monitoring and territorial planning. The approach successfully delineates key landscape features, such as Amazon rainforest, Cerrado vegetation, pastures, and areas of intensive agriculture with double-cropping systems. This innovation holds significant promise for advancing agricultural policy and environmental [...]
